As another example, consider the downward force<span> of gravity that the Earth exerts on </span>you<span> (also </span>called<span> weight). In turn, </span>you<span> exert an exactly equal upward </span>force<span> on the Earth. Together, those </span>two forces<span> form an action-reaction </span>force pair<span>.</span>
Answer:
it's a liquid because it flows
Explanation:
solids don't flow and rocks can be clear too like quartz
your answer will be :
B. <u>Na has a lower</u> <u>electronegativity than H</u>
because Na belongs to alkali metals which are least electronegative (most electro positive) but hydrogen is a non metal, it has higher electronegativity as compared to metals like Sodium (Na).
me too please l need to know how to use this
Answer:
A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a plastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help.
Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle?
by placing the bottle in the freezer to decrease the mass of the air inside the bottle
by pushing down on the bottle to decrease the temperature of the air in the bottle
by placing the bottle in the freezer to increase the air pressure inside the bottle
by pushing down on the bottle to increase the air pressure inside the bottle?
Explanation:
You will need to heat the bottom of the bottle to make gas build up than the ball will pop out.
